Installation Manual

3.7.1 Pre Commissioning MRXBOX MVHR Units

MRXBOX units are designed to ventilate the whole dwelling and must 
not be used during site construction or the clean-up period. Cement 
and plaster dust can be abrasive and can affect fan performance 
and reliability. Please ensure that the filters are checked prior to 
commissioning to ensure there is no build-up of dust or debris.

While the property is drying out, very high moisture levels are likely 
to occur. Therefore it is advisable that if the installation and building 
works are complete the unit is left running. If the building works are 
not complete please close the air valves or cover up the air valves to 
prevent condensation forming in the ductwork and the MRXBOX unit 
due to natural migration of warm air.
